Re: engine swap 351M to 351W
STOP!!!, before getting a new bellhousing, do you have a windsor or a cleveland???
351m is basically a cleveland, and a 351w is a windsor.
Bellhousing, engine mounts, exhaust/extractors, radiator hoses, much wider motor, heaps of things different. Look them up on the web, the 351 and 400m's were used in Yankie F100 - F250's. Reliable strong motor but not performance orientated.
Gimme an old classic cruiser any day over a new car.
I can jump on my fairlane all day long and not even dent it, just bump
a new car 'n' your off to the panel beaters...
